Description
JPEG files uploaded to the Styles page in Content Editor (such as the banner image) display with a red hue when accessing the Captive Portal. This is due to how NAC handles the JPEG multi-channel encodings.
Scope
Version: 8.2.13 and 8.3.5
Solution
Workaround: Use a non-JPEG format (such as PNG).
To be addressed in the next release of FortiNAC.
